Public Event DetailRowExpandedChanged As ASPxGridViewDetailRowEventHandler
The DetailRowExpandedChanged event's data class is ASPxGridViewDetailRowEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Expanded | Gets whether the row has been expanded or collapsed. |
| VisibleIndex | Gets a value that identifies the master row whose expanded state has been changed. |
The event parameter’s ASPxGridViewDetailRowEventArgs.VisibleIndex property identifies the master row whose detail row has been displayed or hidden. To return whether the row has been expanded or collapsed, use the ASPxGridViewDetailRowEventArgs.Expanded property.
Note that the DetailRowExpandedChanged event is not fired when the WebDataDetailRows.ExpandRowByKey method is called.
